ABSTRACT:
A system and method is provided for estimating a sequence of N bits ({circumflex over (x)}0{circumflex over (x)}1. . . {circumflex over (x)}N−1) corresponding to a received sequence of M digital data (r0r1. . . rM−1). The method includes determining candidate sequences of MRSdigital data from a reduced reference sequence space comprising 2NRSreduced reference sequences of MRSreference digital data (s0s1. . . sMRS−1), MRSbeing less than M, and 2NRSbeing less than or equal to 2N. The method further includes making up each candidate sequence with remaining reference symbols to obtain at least one complete candidate sequence of M digital data, and determining the sequence of N bits ({circumflex over (x)}0{circumflex over (x)}1. . . {circumflex over (x)}N−1) from the complete candidate sequences.
